An electronic mail processing apparatus includes a data receiving section (101) that receives mail data including video data or audio data, a cited data detecting section (103) that detects a cited part of the received video data or audio data as cited data from the mail data received by the data receiving section, and a reproduction control section (104) that controls a reproducing method of the received mail data. The reproduction control section (104) controls the reproduction method so that a reproduction method (for example, reproduction speed) for the cited data is deferent from a reproduction method for data other than the cited data in the received mail data.
